If I put my traditional Yorkshire surname on the final result or go with calling it an Intrepid Motorwheel', well the design committee is still mulling that one over.

The basic design is going to be based around the rear frame triangle from a kid's BMX with the bottom bracket converted into a pivot attachment for fastening the whole device onto a bicycle. The engine and petrol tank will be mounted above the wheel and the wheel will be fitted with a mudguard (fender). All very traditional in basic form and layout.
The BMX wheel is ideal for the job with its large heavy duty spindle and wheel bearings as well as being a 40 spoke wheel. It's a front wheel, but that doesn't matter in the slightest as I'm not wanting to attach either a freewheel or a sprocket to it.

I think you're on to something very good. "Intrepid Motorwheel" is also a winner.

There's something wonderfully Edwardian and optimistic about Intrepid anythings.

 

[Intrepid Wheelwoman]

Edwardian and optimistic, - that sums me up perfectly

Intrepid Motor Wheel in a circle with the lettering facing upright so it can be read with Britannia in the middle. Vintage lettering style of course. Perhaps product of The Bee's Knees Manufacturing below that.

Yorkshire? I have a very distant relative who lived there as well as many of my more resent ancestors on my fathers side. The distant relative was nick named Swift Nick and he may be worth a Google.

I'm typing and you beat me to it.

Steve.

 

[Intrepid Wheelwoman]

Gosh, - that's a very interesting ancestor to have Steve

In some areas of Yorkshire folk with my surname are everywhere. A large number of my Yorkshire relatives worked at the main Cadbury chocolate factory at Bournville , - which could explain why I'm so fond of the delicacy.

There's quite a good local signwriters here in town so I most probably will get around to devising a decal design involving all manner of lovely Edwardian heraldry and vintage lettering once I have something workable to attach it to.

 

[fasteddy]

Anne,

That is exactly the Britannia I was envisioning. The motor wheel has my attention for certain.

It's a pity you're not warlike, you could recreate the Minerva.

 

[silverbear]

Hmmmm... "Swift Nick"..."Fast Eddy". You've heard the old expression "the apple doesn't fall far from the tree", no doubt. Just thinkin', there does seem to be a family resemblance, eh?

IWW, concerning the Cag engine check to see if you have a 47cc. According to a thread on PB Planet the 1st four fins from the cylinder base basically disappear into the cylinder barrel as they wrap around due to the increased bore size. The 39cc has very defined fins in this area. If you have a 47cc it may be much less peaky/banded having nearly a 20% increase in CCs and much more usable with a less hyper behavior. Of course there are probably the usual anomalies of Chinese manufacture to dispute this method of identification, but looking at the cylinders on ebay I have seen this difference. After I experiment with jetting I will probably pull the jug to physically identify the bore diameter.

 

[Intrepid Wheelwoman]

The vendor described the engine as being 49cc, but I haven't tried to check out if that is so as yet. I've included a picture of my engine if that's any help.

BOO! HISS! That's a CAG engine IW...
Endless heartbreak, screaming sky high revs and noise, weak clutches and crappy carbs.
BEWARE!

Sorry. Reflex post without reading other comments. Lol!

Yup it sure is They're stunningly cheap to buy and lightweight so I'd at least like to have a play about with one and when it blows up you can tell me, 'I told you so'.

 

[Ludwig II]

When (hopefully soon) I can get back to the Cooper & Ludwig, mine's having the rpm capped and the clutch shoes made heavier, so at least the rpm related problems will be gone. As for making it weedy and low powered, that's the object with this bike.

Heres a pic of a 44mm cylinder(1st) and a 40mm. Notice the fins basically disappear into the barrel on the fist pic and are well defined on the second pic. According to this PB Planet theory my engine is a 40mm/39cc. As with all Chinese stuff measuring is the only sure way to know. Also one cant just order any 44mm big bore kit as there are two wrist pin(I believe you English speaking folks say gudgeon) sizes 10 and 12mm. Nothing is ever simple from the land of the Panda!

Also the lettering on the cylinder indicates(PBP again) the tuning/porting of the cylinder.
